IMPROVEMENT IN APPARATUS FOR COOLING ROOMS.

Specification forming part of Letters Patent N 0. 139,470, dated J une 3, 1873; application filed March 31, 11573.

To all whom it may concern:

Be it known that I, ALEXANDER M. Lus- LEY, of the city of New York, county of New York, State of New York, have invented certain Improvements in Cooling Apparatus for Rooms, of which the following is a specification: v.

The object of my invention is to provide for a simple and effective cooling apparatus for rooms during the hot season, which is simple in construction, does not occupy much space, or require any motive power or machinery, is not liable to get out of order, and is within the reach of the means of the most of families. It consists in placing within a closet, provided with doors, closed at the bottom, but open at the top, mice-safe, which is hung in ropes Working over pulleys and provided with counter-weights, sb that said icesafe can be lowered in 'order to be filled with ice, and again elevated nearly up to the top of said closet. The upper part of the closet, as well as the upper part of the ice-safe, is perforated with holes, and when the ice-safe is in its place in the upper part of the closet, for the purpose of cooling the room, said perforations come opposite each other. The heated air in room rises to the ceiling, and by passing through the perforations in the top of the closet and ice-safe, becomes cooled and descends to the lower part of the room, thus circulating through the whole room and constantly cooling off the temperature.

' In order to describe my invention more fully, I refer to the accompanying drawing forming a part of this specification.

Figure I is a front view of a closet embodying my invention. Fig. II is a vertical sectional view of the same. Fig. 111 is a top view of the same.

A A and A are the back and sides of the closet B. U U are two doors, placed on the hinges a a in front. I) D are the perforations of the upper part of the closet above the doors and the sides, in line with the perforations above the door. E is an ice-safe, with a pipe, as, at the bottom to let off the Waste water. b is a perforated wooden false bottom, placed inside the safe, on which the ice rests. The upper part of this ice-safe is perforated with holes 0 c on all sides. In the middle of the sides inside of the closet are two vertical guide-ways, d d, having grooves e 6, into which the tongues ff, fastened to the sides of the ice-safe E, fit. From the four corners of the ice-safe are suspended four ropes, G G G G, which unite atthe top of the safe, and are fastened to a single rope, F, which runs through a pulley, g, placed in a slat, It, which rests on the top of, front and back, in the center, of the closet. Another pulley, z, is placed in the same slat h, near to the back of the safe. The rope F is conducted through this pulley t and runs down along and near to the inside back A of the closet, and is then conducted over two pulleys, j and It, placed underneath the ice-safe bottom, and is then conducted upward inside in the front of the closet over the pulley H, the loose end of the rope hanging down in the front, inside of the closet. To the top of the ice-safe, in the center of both sides, are fastened two ropes, Z and m, which are conducted up ward, near to the inner sides of the closet, over two pulleys, n n, placed in the center of two slats, S S, near to the sides, which rest on the top parts of the closet, on the front and back of the same The end of the ropes l and m are fastened to the .two counter-weights I and K. Two recesses, o and 10, made in the back corners of the icesafe, allow these counter-weights to move freely up and down in the back corners of the closet. The ice-safe E, standing on the bottom of the closet, is filled with ice, and is then hoisted up nearly tb the top of the closet, so that'the perforations 0 c in the safe correspond with the perforations D D in the closet. The ice-safe is elevated by aid of the rope F, the counter-weights facilitating this movement to such a degree that it is done with the same facility as the opening of a window. Whenin its elevated position the ice-safe is held there by aid of the counter-weights. The lower part of the closet, now being unoccupied, serves as an excellent,- cool, and handy place to preserve and cool elf fluids or eatables.

Having thus fully described my invention, I desire to claim-- The combination of the closet A A A, having doors 0 0, and perforated at its top, with the ice-box E perforated at its upper part, having perforated partitions b, and movable up and down on the guides d d by means of the ropes and weights, all substantially as i Set forth.
